Narrative:

I was sitting at the northern feeder for runway 33 talking with ground control in an effort to clarify a latitude/longitude (waypoint) question on my IFR clearance. When the question was answered, the controller said something like: 'taxi onto runway 15.' I responded with the same: '(tail number) taxi onto runway 15.' as I pulled out onto the runway, I realized I must have misunderstood him. I called the tower frequency and asked for my IFR release. They asked me to taxi off the runway. Immediately after I taxied off, they said if I was ready for release I could take off now. I was, and moments later, I took off. The only traffic I was advised of was a plane (cessna) on 2 mi final as I was given final release. Contributing factors: in my haste to clarify the clearance and working closely with the controller I failed to question what normally I would catch. Corrective action: if after our lengthy discussion the controller had instructed me to now contact tower for release, that would've helped.

Original NASA ASRS Text

Title: C210 PLT HAD RWY INCURSION.

Narrative: I WAS SITTING AT THE NORTHERN FEEDER FOR RWY 33 TALKING WITH GND CTL IN AN EFFORT TO CLARIFY A LATITUDE/LONGITUDE (WAYPOINT) QUESTION ON MY IFR CLRNC. WHEN THE QUESTION WAS ANSWERED, THE CTLR SAID SOMETHING LIKE: 'TAXI ONTO RWY 15.' I RESPONDED WITH THE SAME: '(TAIL NUMBER) TAXI ONTO RWY 15.' AS I PULLED OUT ONTO THE RWY, I REALIZED I MUST HAVE MISUNDERSTOOD HIM. I CALLED THE TWR FREQ AND ASKED FOR MY IFR RELEASE. THEY ASKED ME TO TAXI OFF THE RWY. IMMEDIATELY AFTER I TAXIED OFF, THEY SAID IF I WAS READY FOR RELEASE I COULD TAKE OFF NOW. I WAS, AND MOMENTS LATER, I TOOK OFF. THE ONLY TFC I WAS ADVISED OF WAS A PLANE (CESSNA) ON 2 MI FINAL AS I WAS GIVEN FINAL RELEASE. CONTRIBUTING FACTORS: IN MY HASTE TO CLARIFY THE CLRNC AND WORKING CLOSELY WITH THE CTLR I FAILED TO QUESTION WHAT NORMALLY I WOULD CATCH. CORRECTIVE ACTION: IF AFTER OUR LENGTHY DISCUSSION THE CTLR HAD INSTRUCTED ME TO NOW CONTACT TWR FOR RELEASE, THAT WOULD'VE HELPED.
